ROCHESTER, Minn. – Patients diagnosed with pancreatic cancer can develop elevated blood sugar levels up to three years before their cancer diagnosis, according to the results of a study by Mayo Clinic researchers published the journal Gastroenterology.
“Pancreatic cancer is rapidly fatal after its diagnosis, with average survival of six months,” says Suresh Chari, M.D., a gastroenterologist at Mayo Clinic. “It has also been thought that its course prior to diagnosis is also rapid and that early detection is not feasible. But our studies provide hope that pancreatic cancer can indeed be diagnosed at an earlier stage when it is resectable.”
In the first study, researchers plotted blood sugars levels of patients with pancreatic cancer going back five years prior to diagnosis. They also plotted the blood sugars of a control group of patients who were age and gender matched to the patients with pancreatic cancer. In this group, researchers were able to show that blood sugars rise 30 to 36 months before the diagnosis of cancer.
In another group of patients and controls, researchers plotted blood sugars of nearly 600 patients with pancreatic cancer just prior to surgical removal of the cancer. Researchers grouped these patients by their
